Using the context-sensitive keyword override and final, you can explicitly manage the overriding of virtual functions. In particular, the keyword override solves many issues with difficulty finding bugs in object hierarchies: Methods that should override methods of base classes. The result is syntactica...

It’s as easy as this. Add the keyword, and the compiler checks if this method in fact is overriding a base class method. Thus the aforementioned change of the function signature in the base class will lead to compiler errors in every derived class’ method that declares to be overriding ...
compiling code break just because you were not willing to take some time to choose a less conflicting keyword, then you don’t deserve users. Even C#, for example, overloaded the keyword “delegate” in their implementation of lambda instead of using a keyword like “lambda” or “unnamed”...
